pappo1890 is on a distinguished road
Hi everyone,

I am facing my first multiphase-flow simulation. It is fuel-spray issuing into a chamber together with an air-coflow. I am using Large Eddy Simulations. I have droplet diameters that range between 0.5 and 70 um. The solver is reactingParcelFoam. Is there any criteria you would recommend to choose the lower cell limit? Such as the cell size must be smaller than the smallest droplet diameter?

Thank you in advance for your reply
Pappo
